In shooting, ammunition, bullets etc we still use Grains as unit of measurement. Admittedly many elsewhere in the world us the metric system, and in shotgun cartridges we use grams for weight of shot.
Is there any other industry, trade or profession that use Grains as the unit of measurement.
There are 7000 grains in 1 pound, but is that a US or UK pound?
